Harry Potter star Daniel Radcliffe has ruled out ever having a one-night stand - because he doesn't want his bedroom secrets making newspaper headlines. The 18-year-old has been linked to actress Laura O'Toole, a 22-year-old understudy in his former London play Equus, but claims he would never be silly enough to sleep with a girl without getting to know her first. Radcliffe tells Britain's Heat magazine, "No, I wouldn't (have a one night stand). Because the next few weeks would be awful, worrying she'd sell her story to the press."
